The god didn't answer. His face clouded with anger and he clenched his fists. He stormed past the counter and slammed the gas station door open. The demigods followed.

"Zeus! You big fat bloody liar!" he screamed to the sky. Hazel's eyes widened and she grabbed Apollo by the arm and dragged him back inside. He was still in trouble with Zeus for the whole Octavian went bloody insane and started a war incident.

"What are you doing?" Hazel hissed. "You're going to get yourself killed!"

Hermes didn't look like he cared. He glared at the ceiling before motioning with his arms for everybody to huddle up.

"Zeus mentioned that Nyx had come to him, threatened him with the Seven. Zeus did nothing. He said he'd talked to the fates themselves and they told him it would all turn out well," Apollo admitted.

"Well? My godson is in Tartarus with nobody but Charlie Valdez and a nearly empty backpack! That is not well!" Nico was outraged.

Annabeth marched right up and stuck her finger in the god's face. Apollo let her. But he spoke before she could scream at him as well.

"I know, it's not well. Zeus may have known, he may not have. The fates have a very different version of well than we do."

"Zeus knew?" Jason asked in a dangerously low voice. Apollo nodded. Jason and Percy exchanged a look.

"Apollo, take me to Olympus," Percy ordered.

"That's a bad idea," Apollo advised.

"Tell me that again when your child jumps into Hell."

Apollo nodded in respect and looked at Annabeth. He wasn't going to take Percy anywhere without Annabeth's permission.

"Go ahead. I'll stay here with the kids," she approved. Percy gave her a sad smile. He gave her a lingering kiss, then placed a kiss atop Oscar and Adora's heads. He gave Casey a hug and even though she was angry, she returned it. If something happened to him, Percy had to know he left on good terms. His family wasn't too worried about him. They didn't doubt that he could protect himself against Zeus. And Zeus knew better than to start a war by killing or injuring the Percy Jackson. Especially when one of his kids was in danger.

Apollo took Percy's arm and gave the group a warning. They closed our eyes and when they opened them, Percy and Apollo were gone.

The others lingered in the gas station for a few more minutes before deciding that this was going to take awhile. Apollo would know where to find them. They grabbed their supplies, slapped a stack of bills on the counter, and headed back towards the ship.

"Where's Percy?" Leo asked glumly when the group got back to the Argo. By the puddle on the floor, Annabeth assumed he'd been talking to Calypso. He'd Iris Messaging her every day.

"On Olympus, yelling at Zeus."

Leo nodded, not bothering to ask why.

(Meanwhile, with Percy…)

Percy Jackson's hands were trembling. After all they'd been through. After all he'd been through. He was ready to storm up to Olympus and tear them down himself, bare handed. He was willing to kill anything that stood in his path. Apollo had left once he'd reached the doors to Olympus, knowing it would about to become heated in the throne room.

Zeus appeared before him. Percy did not bow. He stood and glared at the god, then showed off his sword.

"Perseus-,"

"My child. It took my child," Percy growled. A dangerous glare of warning gleamed in his eyes.

"It was necessary-,"

"Necessary? Do you know where he is?!"

Perseus Jackson wanted to drop to his knees and scream. He wanted to run the king of the gods through with Riptide. Instead, he concentrated on not letting his tears escape in front of Zeus.

"Annabeth and I, we saved your silly immortal lives more than we've lived our own. We gave up everything. After all we've been through, started a family, gotten to the point where we don't wake with nightmares each and every night, we were finally happy! But my child? My son! He was the first of any happiness Annabeth and I experienced since you gods ruined our lives. He's the reason we're sane. He's already saved your worthless ass more times than you have saved yourself. Do you know where he is because of you?"

The tears came anyway, but Percy knew the ruler of the skies was still threatened by him. They both knew Percy was capable of killing him right then and there if Zeus made one wrong move.

"No, Perseus."

Percy closed his eyes, haunted with images of a place he never thought he'd have to think of again. "My son is in Tartarus."

Zeus took a step back. "It cannot be true," he protested.

"I don't care what you think, it is true. I don't know what has happened to him, or what is happening. Now tell me, is he alive?"

Zeus didn't answer. "

IS MY SON ALIVE?" Percy raised his sword and pointed it towards the god.

"I do not know," Zeus answered.

Percy trembled with anger and grief. "He's sixteen years old. He's a child, Zeus. You've had children, but they are nothing but pawns to you. Jason Jackson is not one of your pawns. He is my son. And if I do not get him back, you will regret every decision you've ever made. If there's any chance that he's alive, you will help me get him back. If we have a chance to save him, to help him, and you don't take it, I will destroy you," Percy threatened. His voice was cracking, tears swam down his cheeks.

Zeus sighed. "I assure you-,"

"I swear it on the River Styx. If my son dies because you don't help him, I will kill you and make sure you can never come back."

Zeus's face went dark. "You should not threaten a god, Perseus."

Percy's expression was much more than grief, almost causing the god to take back his words. "You should not have threatened my family, Zeus."

Once he left, Percy found Apollo outside the throne room. "Bring me back to my family, please."

Hermes nodded solemnly and took his arm. He didn't teleport quite yet.

"Did you find anything?" he asked.

Percy sighed. "I don't know. The news isn't great, but we have no way to know for sure what happened."

Apollo nodded and they evaporated in a bright light.

When Percy opened his eyes, he was standing on the bow of the argo.

Casey found him first. "Dad!" She ran towards him and Percy wrapped her in a hug. He would never take advantage of his family. They were too important. He still had three kids that needed him.

"It's ok honey, are you ok?" he soothed. His previous demeanor was gone in an instant. Above him, Zeus wondered how a child's love could really change a man so much. He wondered how anything could change a murderous attitude like that.

"Are you? You've been gone for two days!"

"I'm fine. I'm so sorry, I didn't realize how drastically different the time would be on Olympus," Percy apologized. Casey looked up at him with big sad eyes, wishing for the news Percy didn't have.

"I don't know, honey. Zeus doesn't know either, but if he gets any news he'll tell us," he offered.

"How do you know he'll tell us anything?" Casey spat towards the sky.

"Trust me, he will."
